Problems solved by technology
Therefore, if the height dimensions of the external terminals 303 and 355 are staggered, the flatness with respect to the printed wiring board will deteriorate, and there will be problems in surface mounting such as the operation shaft is not vertically erected with respect to the printed wiring board.
[0008] However, since the external terminal 355 of the fixed contact box 350 has a height position based on the rear surface of the mounting base 300, the external terminal 355 has a shape that includes the dimensional error of the two components of the mounting base 300 and the fixed contact box 350. to determine the size, and thus the external terminal 355 of the fixed contact box 350 cannot achieve sufficient height accuracy

Embodiment Construction
[0039] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In this embodiment, an encoder switch is taken as an example of a rotary electric component, but a varistor which is one of the rotary electric components is also applicable.
[0040] figure 1 It is a cross-sectional view of a rotary electric component with a push button switch according to an embodiment of the present invention, figure 2 It is an exploded perspective view of the rotary electric component with push button switch of this embodiment. The operating shaft 1 is supported by a bearing member 2, and the operating shaft 1 is rotatable and press-operable, and a pressing member 3 is fixed to one end of the operating shaft 1 (the end not protruding from the bearing member 2). A sliding member 5 made of an annular metal plate as a sliding contact is fixed behind the rotating member 4 , which is installed in a state where it can slide in the direction of...

The invention provides a rotation type electric part with button switch, which can increase the height and precision of the terminal of rotation type electric part side and the terminal of button switch side relative to print circuit board, therefore the good surface actual installation is realized. The prejection of a button contact box installed below goes through the abjunction part of the coder contact box and connects with the reference plate for box, therefore the height relative to print circuit board is set. Alternately, the coder contact box installed upside makes the integrative terminal extracting part go through the side face of the button contact box and extend to the underside of the button contact box, and the prejection contacts with the box using the reference plate, therefore the height relative to print circuit board is set. Thus the height and precision of the terminal of button contact box is free from effect of deviation in height of the coder contact box.
Description
technical field [0001] The present invention relates to a rotary electric switch with a push button that functions as a push button switch through the movement of the operation shaft in the axial direction, and functions as a pulse switch or a variable resistor through the rotation of the operation shaft. part. Background technique [0002] Conventionally, various rotary electric components with push button switches have been proposed (for example, refer to Patent Document 1). A rotary electric component with a push button switch described in Patent Document 1 such as Figure 9 As shown, a rotating body 310 is held in a cylindrical accommodation space formed on the mounting base 300, and the rotating body 310 is rotatable. The front end portion of the cylindrical portion 311 of the rotating body 310 is inserted into the circular opening 301 formed on the bottom 300a of the accommodation space of the mounting base 300, and the portion of the cylindrical portion 311 extending...
